Geographical information system applications in environmental impact assessment

The effects of alternative agricultural land use scenarios in terms of environmental impact assessment on surface and ground water were simulated by means of combined socio-economic and environmental models. The economic model produced and evaluated alternative farming systems, defined in terms of land use (in farm crop allocations and regional statistics of crop distributions) and cultivation practices as influenced by different macro-economic scenarios of agricultural policies. These scenarios were defined on the basis of the present Common Agricultural Policy of the European Union and possible future measures for reducing the impact of current agricultural systems on the environment. The farmers' decisional process has been simulated with multi-objective functions aimed at maximising profits and minimising risk. The methodology for the environmental impact assessment of farming systems is based on a simulation model for non-point source agricultural pollution which determines the impact of agriculture on a single field basis as influenced by environmental variables (soil and climate) and farmers' decisions (crop, soil management, fertilisation, etc.). The results obtained from this model were used to calculate a series of comparative indices capable of describing the effects of the use of fertilisers and pesticides on surface and ground waters. A geographical information system supported the spatial data management in particular for: a) the definition of simulation environments; b) the integration of physical and statistical geographical information; c) the cartographic presentation of results and the comparison of alternative scenarios. The model has been applied in the area of the Watershed of the Lagoon of Venice (WLV), located in northern Italy and has demonstrated how alternative policy scenarios determine not only significant variations in the overall environmental impacts in the study area, but also remarkable differences in their spatial distribution.

Post Industrial

Ongoing transformation of coal industry taking place in Silesian Voivodeship lead to increasing number of characteristic objects and post-industrial areas. Most of them are degraded and vacant even if they own resources of measurable natural or socio-economic value. Therefore effective scheme of their revitalisation is a high priority target for regional authorities and society. Multidimensional approach to the analysis of post-mining areas requires ensuring proper scope and quality of data, integrating various areas of knowledge and information. An example of complex approach is an information platform based on analytical and expert modules the OPI-TPP system, which is a tool to support decision-making processes on the future use of post-industrial areas. OPI-TPP based on Geographical Information System is an integrated tool dedicated for environmental impact assessment and provides measures that are necessary for regional and local stakeholders and reinforces decision making process. This paper describes the methodology of post-mining area assessment in environmental impact aspect and exemplary applications with the use of the platform. The main functional relations of the system were presented, allowing to use the available range of data and analysis modules for the purpose of supporting environmental impact assessment for post-mining areas management in the Silesia Voivodeship.
